I Each ,,cord.-after passing through tlie corresponding, aperture, 26 is knotted :alset, 271 It: will j be; apparent nowthat ag ng, rollen'isfrevolved in one direction the cords will be wound around corresponding end members. The curved flanges provided at the end. oi' each end member causes the cord to be wound in jHXlZLPUE-YQtl turns-1 rather than in S'dpci imposed turns or convolutione. Obviously. ijl both cords did not wind in the same inan ner at all tiinei: one cord would raise its load taster than the other. which in tine instance would result in uneven running; oi? the moving; parts and inclination (it the shade and its; customary spring: and roller 29.

The shade roller 29 is held by tfavcline lil'llt'lCC't-i Eli one being -arried at the lower end oi? each correspoinlingg cord, apertures 2h") are provided for tyinp; a cord thereto.

Fhe plurality of notcaca also provide for changing the eh ration ot the roller with regard to the bracket. A shade and a roller having a sunall number oi convolutions should he -ar ricd by the uppermost set of slots, oi? a pair oi? brachete, so that it 111a be moved up into actual abutr'ient with the upper roller with out ierinitt'ing the traveling brackets to ride too high.

For iach traveling bracket: there provided an elongated guide n'ieinber iii of a length corresponding to the vertical travel out the shade roller. Each guide member is of tubular construction of square cross aection and is Pl'O'Vltlttl with a era-extensive slot l? in which the corresponding pintle rides and guided. The interior space lel,

enclosed by the walls ol? the guide member,

tlln'iously, when this :torni of bracket is made use oh the elotted guides will lie perpendicnlar with the ahade 'arrying roller thereby making it necessary to provide the traveling bracket or nnnate with an extenrion each as it? that receives the pintle ol the shade roller (see .llig. V

l have :tound that; by providing the lixed pintle ill with a alight; llange or head on its outer end. the end oi? the roller provided with each pintle cannot become accidently disengaged from its; biaring' bracket.

The (uicratioin advantageo and lllct'lltltl oi? :iEiOllllJly oi? the parts apparent from the :toregoine'. Jo; to the actual ope ation of the device as a whole, it will be seen that with the aid of the lower cord, the upper roller may be turned in either direction and may be stopped a 1 an desired point, as in the care oi? any common uhade. Thus, the elevation oi the shade may be changed at will. The shade in round upon, or unwound 'llTOlll its roller in the usual manner. N hen the travelii'ig brarhetu are moving, they are guided by the guide n'ieinbers, and when the shade roller statioi'iary, the pintles and braclzets being guided by the guide 111e1nhe a, hold the startle roller from being moved forwardly by whipping ot the shade. The curved 'llangeu provided by the end members of the upper roller, 'novides :lor even rolling; of both cords and keeps the shade roller always in a true horizontal position.

It will be apparent now that, I have pro vided a device of the class described, in which the shade, shade roller, cords and roller supporting brackets are well guided and governed to produce smooth and ellicient ope 'ation at all times, together with t-so too

neat appearance, and while Ihave shown and described a specific embodiment of my invention, I do not limit myself to any specific construction or arrangement of parts,"

and may alter same as required, without enlarging the scope of my invention, within the appended claims.

I claim as my invention:

1. An adjustable window shadecomprising a roller, pintles projecting from the ends thereof, fixture plates in which said pintles are mounted, a slotted ear projecting from 7 each plate, which car is adapted to receive an attaching screw an ofi-set ear depending from each plate, a channeled guide member having its upper end embracing the'depending oif-set ear of each plate, the lower end of each guideway being provided ,with a screw recelvlng slot, runners arranged for slldlng movement in the channeled guideways, cords secured to said runners and to the end portions of said roller, a cord secured to and 1 depending from one of said runners and a shade carrying roller having its pintles engaged in said runners.

2. In an adjustable window shade,a roller,

pintles projecting from the ends thereof, tui bular members projecting'from the en'dsof said roller, the outer portions of which tubu lar-- members are flared outwardly, fixture plates having flared edges that enclose the flared edges of the tubular members on said roller, said fixture plates being provided with apertures thatreceive the pintles in the ends of said roller, a slotted ear projecting from each fixture plate, which slotted earis adapted to receive anattaching screw, an offset ear depending from each fixture plate to one side of the center thereof, channeled guideways having their upper ends embracing the offset ears on said fixture plates, the lower ends of said guideways being provided with screw receiving slots, runners arranged for sliding movement in the channeled guideways, cords having their lower ends connected to said runners and their upper ends connected to the outwardly flanged portions of the tubular members on the ends ofsaid roller and a shade carrying roller arranged between and supported by said runners.

3. In an adjustable window shade, a pair of fixture plates, a slotted ear projecting from the lower portion of each plate forthe reception of an attaching screw, an ear depend ng from each fixture plate, said e'ar being ofl set relative to the center of said .ment in the channeled guideways and connected'to said cords and a shade roller provided in its ends with pintles that are mounted in said runners.

I 4. In an adjustable window shade, a fixture plate comprising a disk, a curved flange encircling a substantial portion of the edge of'said disk, a slotted ear'projecting from the lower portion of said disk and an ear depending from said disk, which ear is OK- set with respect to the center of the disk and with respect to the vertical by the body of the disk. r

5. In an adjustable window shade, a fixture plate comprising a disk, a curved flange encircling a substantial portion of the edge of said disk, a slottedear projecting from the lower portion of said disk, an ear depending from said disk, which ear is off-set with respect'to the center of-the disk and plane occupied with respect to the vertical plane occupied 7 by thelbody of the disk, a dome-shaped projection at the center of said disk and, which dome-shaped projection is provided with a pintle receiving aperture.

In testimony whereof I aflix my si nature.
